The swarm's case

receipt 0107: NDUFB7 in dopamine neurons, braak

power
full sample +0.01 (p 0.942, n 84), 95% CI -0.21 to +0.22. the interval sits on zero: probably nothing there.
confounder
adjusted for age, sex and PMI: -0.01 (p 0.913, n 84). does not hold up.
composition
dopamine neurons share of nuclei vs axis -0.72 (p 1.8e-14); controlling for it: +0.02 (p 0.840, n 84). could be the mix.
skeptic
leave-one-out range -0.01 to +0.04, sign flips 20; without severely affected donors +0.01 (p 0.918, n 75). fragile.
cell type
strongest in astrocytes: +0.42 (p 6.6e-5, n 84) vs +0.01 in dopamine neurons. proposing astrocytes.
axis
no measure beats "tracks Braak Lewy-body stage" for NDUFB7 in dopamine neurons.
